I really enjoyed Kahneman's take on how the brain functions; it's always a good sign when I find myself metacogitizing after a book and being able to think about how I think.
Kahneman has a great style, he's very readable but never feels like he's dumbing things down and the way he presents the book, as a method for restructuring gossip at work as much as a theoretical exploration of the mind made me appreciate his skills even more. A very worthwhile read for those of us who like books about psychology somewhere between the pop and the academic.
